  • Patent number: 10646326
    Abstract: The present disclosure relates, in some aspects, to orthopaedic implants for securing soft tissue to bone and methods for using the same. One particular implant comprises a first exposed porous surface region, having pores for promoting bone ingrowth, and a second exposed porous surface, having pores for promoting soft tissue ingrowth. At least some of the pores of the first exposed porous surface region may be seeded with osteocytic factors and at least some of the pores of the second exposed porous surface region may be seeded with fibrocytic factors. Such orthopaedic implants can advantageously facilitate regeneration of the soft tissue to bone interface.

  • Patent number: 9918845
    Abstract: Augments systems and methods for attaching two or more augments to an underside (50) of a tibial baseplate (16) are disclosed. An augment system (100) can include a first augment (102) having a superior surface (106) and an inferior surface (108), the superior surface configured for attachment to the underside of the tibial baseplate. The augment system can include a second augment (104) having a superior surface (110) and an inferior surface (112), the superior surface configured for attachment to the inferior surface of the first augment. The first and second augments can be formed of different materials. One or more additional augments can be used with the first and second augments, and the augment system can be stacked on a resected surface of the tibia. In an example, the augment that directly contacts the resected surface of the tibia can be formed of a porous material, such as to facilitate bone growth.

  • Patent number: 9730743
    Abstract: A trochanter attachment device can include a plate for attachment to an inner portion of a greater trochanter of a femur, a collar for attaching the plate to a hip implant, and a fastener for securing the collar to a hip implant. The trochanter attachment device can include a groove or other feature for receiving a reinforcing material, such as a wire or a cable, such as to reinforce an attachment of the device to the greater trochanter and/or the hip implant. The trochanter attachment device can include an insert attachable to the plate and configured to attach the plate to the greater trochanter. All or a portion of the plate and/or the insert can include a porous material, such as to promote bone ingrowth of the greater trochanter.

  • Patent number: 9579141
    Abstract: An orthopedic device holder and related system and method are disclosed. The orthopedic device holder can include a body member, a cannulated plunger, and a resilient member. The body member can include a longitudinal main body and an extension portion. The cannulated plunger can be slidably mounted inside the body member and movable between a first position and a second position. The plunger can be configured such that in the second position, a plunger distal end extends past a main body distal end, and in the first position, the plunger distal end assumes a more proximal position. The resilient member can be positioned adjacent a plunger proximal end and can be configured to urge the plunger towards the second position. The extension portion of the body member can project distally from the main body distal end and can include a locking member, which can be configured to fit into a mating recess of an orthopedic device.

  • Patent number: 9517138
    Abstract: A tibial support structure includes a platform portion and a medullary portion that are monolithically formed as a single piece. The medullary and platform portions of the augment component are adapted to accommodate and mechanically attach to a tibial baseplate, and are individually shaped and sized to replace damaged bone stock both within the tibia, as well at the tibial proximal surface. The monolithic formation of the tibial support structure provides a strong and stable foundation for a tibial baseplate and facilitates restoration of the anatomic joint line, even where substantial resections of the proximal tibia have been made. The tibial support structure may be made of a bone-ingrowth material which facilitates preservation and rebuilding of the proximal tibia after implantation, while also preserving the restored joint line by allowing revision surgeries to be performed without removal of the tibial support structure.

  • Patent number: 9492178
    Abstract: A method for implanting porous spacers (100) for foot and ankle fusion between separate bones of a joint or between two segments of a single bone following an osteotomy procedure. Such spacers may be used in conjunction with an ankle resection system which includes a resection frame (150 and a resection guide (1780). The resection frame can be anchored to the distal tibia and/or the talus and provides an opening (155) through which a bone cutting element can pass for cutting underlying bone. The resection guide can include one or more cutting slots (160,171,172) and the resection guide can be coupled to the resection frame with the one or more cutting slots positioned over the opening in the resection frame so that the bone cutting element can pass through the one or more cutting slots and through the opening in the resection frame for cutting the distal tibia and/or the talus.
